The following task has a new comment added:

FS#453 - Dune::BlockBitField is not a replacement for std::vector<Dune::BitField>
User who did this - Carsten Gräser (Carsten)

----------
Yes in inherits all methods but they are not found by name lookup (clause 14.6.2) without a 'using' declaration. I know that BitVectorConstReference plays the role of a const reference. But consider the following case (which I used):

template<class BitSetType>
void f(const BitSetType b)
{
  std::cout << b[0] << std::endl;
}

Then f(BS[0]) does currently only work if BS is a _const_ BitSetVector which is strange. Thus I propose to add the 'using' declarations and everything will work as expected.
